Update Dec.10 2023
1. Add “spool holder Max” version, more biger size spool fit in.
2. Modify the length to make two version fit in A1 mini printer.
Please note that the “lite” version is recomended if you don`t have special bigger size spool. The “Max” version may not easy to be print.
The rollers may partially stick with ring together, it may need you loose them by knife.
